UNITED STATES PATENT OFFIC DANA H. BENJAMIN, OF UTIOA, NEW YORK, ASSIGNOR TO EDWARD HURLBURT, or sAME PLAoE.

WASHING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 402,222, dated April 30, 1889.

' Application filed November 3, 1888. Serial No. 289,942. (No model.)

To all whom, it may concern.-

Be it known that I, DANA H. BENJAMIN, of

. Utica, in the county of Oneida and State of New York, have invented certain new and useful Improvements in a Fluid-Circulator Connected with a Washing-Machine; and I do hereby declare that the following is a full, clear, and exact description of the invention,

' which will enable others skilled in the art to which it appertains to make and use the same,

1 reference being had to the accompanying .r so

drawings, and to the letters of reference marked thereon, which form part of this specification. I

My invention relates to a fluid-circulator, and it consists in the mechanism hereinafter pointed out and claimed.

In the drawings,Figure 1 represents a side elevation of a washing-machine with my improvement, the broken lines showing portions of the frame removed. Fig. 2 is an endview of a vertical cross-section, showing the door of the rotating cylinder open. Fig. 3 represents details of construction, showing a portion of the piping and cylinder in sections to more fully illustrate the construction; "and Fig. 4 represents a vertical central. section of the hollow stud.

In the drawings similar letters and figures of reference refer to corresponding parts in. the several views. I provide suitable frame, 1, in which frame I provide stationary tank 2, in which is mounted perforated intermediate cylinder, 3, journaled in bearings 4 4 in the frame, so as to be rotated by any well-known mechanism.

Rotating cylinder 3 is provided with perforations 5 inthe walls thereof to allow the movement of the fluid in the process of washing. I provide hollow journal or bearing 6, which opens into rotating cylinder 3.

The fluid employed in washing is placed in stationary tank 2 and circulates through apertures 5 in rotating cylinder 3. For heating and circulating the fluid through the cylinders and the clothing, which is inserted in cylinder 3 through opening 7 which is closed by door 8, Fig. 2, I provide connecting-pipe or passage-way 9, one end being connected with the hollow stud at 10, Fig. 1, and the, end of stationary tank 2 at 11, forming an' open passage-way from cylinder 2 through hollow bearing 6 in rotating cylinder 3. For

pipe having nozzle let, Fig. 3, of smaller diameterthan the passage-way, into which passage-way the nozzle of the steam-pipe projects in the direction of the flow, as indicated by the flight of the arrow in Fig. 1,-so that when the steam-pressure is applied to the fluid in the passage-way it impinges against the same, thereby creating and maintaining a current of fluid which moves in the direction of the flight of the arrow and is discharged into rotating cylinder 3 through hollow stud 6 onto or into the clothing in the cylinder, thereby circulating the fluid through the clothing and cylinders and tank. The nozzle of the steam-pipe, which enters the pipe and passage-way 9, is of somewhat less diameter than the passage, so that by providing pipe '16, controlled by cook 15, the fluid will be free to pass out of stationary tank 2 by flowing past the nozzle 14, Fig. 3, of the steam-pipe, which enters passage 9, thereby emptying the machine of the fluid, if desired.

For mixing bleach or bluing, or both, with the fluid during the washing process, I provide supply-pipe 1'7, controlled by cook 18, so that when the cock is open the bluing or bleach, or both, is free to flow into passageway 9 and mix with the current of fluid as the same is moved through the passage and hollow bearing onto or into the clothing in rotating cylinder 3.

It is obvious that outlet-pipe 16 and pipe 17 may be dispensed with and yet furnish a complete working mechanism.

D. H. BENJAMIN.
